Obviously you can operate at a mile if you up the wattage, but then
that's illegal, and if it weren't, there would be pirates, jammers, who
knows what else.

If you're just talking about the occasional mile span to cross a river
or something, I think you might be able to span it with one of those
green laser pens, suitably modulated to carry everyone's conversations.
It would have to be kept precisely aimed, there'd need to be a low
frequency filter to filter out vibrations, there must be line of site,
and creating a man in the middle attack would be just a matter of
intercepting and retransmitting the green light.
